FLUSH- TANK.

Application filed July 193i whom may GOTLFGTH.

r I, FREDERICK Mi IT? a Lizen the United States, r12 siding at Sr. Louis in the Stat-e of lvlissouri, have invented certain new and useful in;- prororoents in Flush Tsnks of which the following is spscifiestion.

3 his invention relates to irnproven'ients in flushing tanks, and has for one of objeots to im rove the construction and irroreaso the e tieney and utility devices of this character Another object of the ini 'enfiiotn is to pro ride a simply constructed devise including an inner tank having a discharge at one and mounted for both vertical and rotary movement within. an outer tank and. sup ported by counterweights and connected with a controlling valve, whereby the opera t-ion of the inner tank is eltlkeoted and tho inner tank caused to automatically its normal position with the discharge dirooted upwardly to receive its supply of Water for the next operation.

A further. object of the invention is to provide a simply constructed device inelnd ing an inner tank which may be installed in t main or outer flush tank of the ordinary mnstruction Without material. change in the main tank or its attachments.

With these and other objects in View, the invention consists in certain novel features construction as hereinafter shown and described, and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of tho invention; Figure 1 a side elovalion of i-he improved attachment located within an ordinary flushing tank, the flushing tank he ing in section; 2 is a transverse sect on onithe line 2--Q of Fig. 1; Fig. 3 is a section on the line 3--3 of 1.

Corresponding and like ports are referred to in the following description and indi oat-erl in, all the views of the aceornparqziug drawings by the some refers-me characters.

The ii'nproveol device compass an attochment tooe lot-ate l within a H sll tank I indicated a Whole at 10, preforahly o tie form slimvn but which may he of 0" forms, and it is not desired to limit device to any special term of the flush Speeifieetios oi Letters Fatent Patented May 16, 1916.

Serial K0. 38,573.

The tank 10 is provided with an intake l and a discharge 12 of the usual conemotion, The controlling valve of the inm'r pipe 11 is represented conventionally at and is preferably of the ordinary gate form and having a stem At its upper end, the intake 11 is curved inwardly and toward the center of the outer tank 10, as indicated at 16, to discharge nearer the center of the outer tank the object to be hereafter explained. Supported upon the ends of outer tank 10 are hanger devices lS the upper ends of the hanger devises being preferably in hook-like form, as indzroted at il 20, to engage over the upf: of the ends of the outer tank. Motel. 2l-a22 to the lower ends of the hanger devioes 17-18 is a U-shuped frame, represented as a Whole at 23, and extending toward the roar of the outer tank 10 and provided with relatively heavy weights 24 suspended by hails from the mem-lier 23.

The member 23 is provided with notches to receive the nails of the weights so that the wei hts can be adjusted upon the member 23. The bearings for the pivots 2l22 open downwardly and are spaced away from the ends of the U-shaped member 23 and the terminals of the member 23 are provided with upwardly opening bearings 25-26.

An inner tank, represented as a Whole at 27, and preferably of glass or like material and cylindrical in shape is provided with trunnions, indicated at ill-29, and engaging: in the bearings 25 26. The member 27 is provided with on opening 30 at one side and \vniglited, as shown at 31, preferably increasing the thickness of the lower wall at the side opposite to the opening 30. By this means. when the memher 27 is empty, t 'gllted portion 31 will maintain the opening 30 aqnvardly. as will be obvious.

.l xrme il upon the shell of the member 27 is on outwardly rind longitudinally directed chamber or pocket-like receptacle upon the inner tank 27 and opening into the interior of the smne. The chamber is pro rid -l with a plurality of minute draining 34, the ohjeet to he hereinafter i ivoted at 35 to one of the hangers, for

instanee the hanger t is a lever arm represented as a whole at 313. the pivot heing loeated intermediate the lever with one end of the lever heavier than the other end. The lighter end of the lever is redueed and adapted to engage a stud 3T projeeting from the adjaeent end of the inner tank 27. pull menlher. for instant-e a ehain lh. is eonneeted to the heavier end ot the lever arm 2hand passesover a guide pullev El! and theme through one end of the outer tank and depend to a veonveuient point for the operator and terminates in a pull handle 40. .\ttarhed to the hanger memher 18 is a stop ll to limit the movement of the lever arm H stop l;' is attarhed to the inner fare of the rear wall of the outer tank to limit the downward movement of the hail uiemher 2-").

.\ttaehed to the suppl eondlletor ll is an arm t l. aml pivoted at l4 in the free end ol the arm is a hell-erauk lever 45. The hell] (rank lever is pivoted at one end at ill to the stem [.1 of the valve l and provided with a pull rod 47 at its other end. .\t its lower end the pull rod lT is ronneeted to a elip l5 attaehed to the rear portion ol' the hail L l. l this means it will he ohvious that hen the hail 3 1 moves into its downward position the valve til will he artuated through the eonneeting memhers l5 and IT. l v this simple arrangement. it will he oh\'i ous that when the lever arm lt' is aetuated h a pull upon the memher 23% the terminal of the lever aetiug upon the stud t? will rotate the inner tank 27 on its trunuious 2 *1! a distanee sullieient to eause the inner tank to he partly overturned. When the inner tank ii is tilled with water. the weight will. he sutlieient to maintain the shorter ends ol' the l'rame 311 in lower position and the weights l in upper position. as shown in Figs. 2 and \\hen the parts are in this position. it will he noted that the hell erank l5 aeting through the link eonnerting memhers lT will 'maintain the valve 1 elosed and slult (ill the How through the intake ll.

\Yheu the tlushing operation is to he ])l'n dueed. a downward pull, upon the lueluher its will eause the memher i to rotate the inner tank L? for a rertain distanetand thus eause the weighted portion Ill to assume a position at one side of the renter ol' the inner tank and to eause the major portion ol' the weight of the nater to overeome the inertia ol' the weighted portion ll and eompletelv overturn the inner tank whose eontents are quieklv diseharged through the opening 210. .\s 4hinner tank 3T rotates to hring the opening Il l ill a downward position. the relatively small lltbtltthllltt ehainher I32 will he tilled with \\':Ht'l' and islarge enough to eo|l tain a sullieient quantity of water to maiir tain the tank in its downward position suppl v ll.

against the pull of the weights 24. as shown in Fig. 3. and thus hold the valve 1 3 closed. The water in the poeket 23; will gradually tlow out through the"oritiees H and when this takes plaeethe weight of the tank :24 helow its eenter is lessened to an extent suftirient to permit the weights 'l-l to return the tank '37 to its upper position. thus eansing the lever meehanism -lf lT to open the valve l3 amt permit the water to How through the At the same time that the poelwtdike ehamher 3:2 is emptied, the weighted portion 51 of the inner tank again heroines aetive and instantly returns the innertank :27 to its upper position.

lrs helore stated. the terminal 16 of the intake 11 is extended toward the center of the outer tank. and is in position to discharge through the opening of the inner tank" sition and the valve 13 open until the water llowing into the inner tank rises to a certain Plttltttl'llllllttl height. and when the inner tank is thus supplied it. will he depressed against the pull of the weights l4 and again elose the valve 1 5. When the tank 17 is thus restored to it's l'ormer normal position, the stud 3T will likewise he disposed in its former position relative to the releasing inene, her i i. as will he ohvious.

The improved deviee is simple in construction. ran he inexpensively manntaetnred and applied. and h slightly modifying the lengths of the lever meehanism hetween the l'rame 2-; and the valve 13 the improved deviee may he applied to any of the various l'orms ol' llush tanks manut'aetnred.

'lhe stud 37 engages the memher .33 when the tank '27 is overturmal, and thus prevents the tank lrom eompletel) overturning, but moves over ahout one half a lull revolution and thus insuring its return to upright positi n alteneaeh tlushing operation.

Having thus deserihed the invention, wlr't is elailned as new is:-

i In a deviee ol' the elass deserihed. an outer tank having an intake provided with a eontrolling valve. a voke t'rame ineluding sides spared apart and eaeh provided with an upwardlv opening hearing and a downwardl v opening hearing. suspension devices engaging said outer tank and having journals engaged hr the downwardly opening hearings. eonneeting means hetween said \'ol\'e l'rame and said eontrolling valve. an inner tank mounted for rotation in said upwardlr opening hearing and having an opening in one side to reeeive the diseharge from the intake when in one positioniiuul means for initially overturning the inner tank.

"2. In a deviee of the elass deserihed. a tank having an opening in one side and Weighted at the opposite side, a supple mental chamber communicating with the interior thereof and having drainage orifices, means for mounting said tank for vertical and rotary movement, a supply device in cluding a controlling valve, means whereby the vertical movement o f said tank controls the movements of the valve, and means for initially moving said tank rotatively, the

contents of the sulciplemental chamber oper- 1O :iting to hold the rotative fink in overturned position.

In testimony whereof I ailix my signature in presence of two Witnesses.
